A detail construction of such guide and the To enable others skilled in the art to make clamp for holding the drills is therefore not o 40 and use myinvention, I will describe the same considered necessary. The cylinder is moved more fully, referring to the accompanying upon the swinging frame by means of the drawings, in which feeding screw S which is operated by the hand Figure l is an end view of the wall-chau- Wheel a".

This extension 16 is secured within this seat by means of the strap 15 and by suitable bolts, and it can be adjusted longitudinally in its seat according to the position of the drills, or longer rests may be substituted for the rest employed with the shortest drills, as drills of different lengths are secured in the clamp. The rest 14 is of no greater width than the drills, and such rest can therefore be arranged to extend within the channel cut by the drills and give support to the same some distance from the point where they are connected to the clamp H.

In order to operate the swinging frame, it is necessary to provide mechanism which will move the sameat a practically uniform speed, both in the upward and downward stroke of the swinging frame, so as to provide for the cutting of the channel during both movements of the frame, and such mechanism can of course be operated by suitable gearing; but gearing connections have the disadvantage of difficulty in changing the speed, and though such gearing devices would be included in my invention, where they are the equivalent of the device described, yet I prefer to employ the hydraulic mechanism shown. For this purpose I employ the reservoir Z, for oil or other suitable fluid, and the pump Y, the reservoir Z having flexible hose or like connection 9 leading to the upper part of the hydraulic cylinder to above the piston. The reservoir has also the suction pipe 2 leading to the feeding end of the pump Y, and the pipe 12 is connected to the discharge end of the pump, while the by-pass or return pipe 3 leads from the 'pipe 12 back to the suction pipe 2, the return pipe 3 having the valve 10 therein. Leading from the discharge pipe 12 to the reservoir Z is the pipe 13 in which is located the regulating valve 11 to regulate the pressure brought upon the piston within the hydraulic cylinder, as hereinafter described. Extending from the pipe 12 is the pipe 8, part of which is made flexible, such as by a hose connection, and which leads to the hydraulic cylinder directly below the piston, or indirectly', such as through the trunnion, for supplying the fluid under pressure thereto. In this pipe is located the regulating valve 7 for the purposes hereinafter described. The suction pipe 2 has also the globe valve 6 for closing communication between such pipe and The construction of the regulating valve 7 is shown in Fig. 3, the valve having the body portion a, the entrance port a, the discharge port.a the check valve 0. in the diaphragm a, and the pressure regulating valve a in the same diaphragm, said valve having the spring a, the pressure of which is controlled by the handle 617. The diaphragm a within the valve is U-shaped inform and has the two openings a a", the pressure valve 01. being seated in the opening a while the check valve a is seated in the opening a?.- By suchconstrneQ tion it will be seen that the liquid under pressure entering through the openingfla" opening a", such being the course of the liquid flowing from the pipe 12 through the pipe close the check valve a and can only pass through the valve by raising the regulating.

8 to the hydraulic cylinder; but when the liquid flows back from the 'cylinder'it "will valve a and this valve can be regulated by compression of its spring a so as to exert the necessary force for regulating the descent of thepiston within the cylinder. Thevalve 11 is a simple pressure regulating valve which is set to regulate the pressure of the liquid flowing into the reservoir, but which prevents the liquid flowing back from the'reservoir intothepipe 12. r

As the apparatus is so arranged, the valve 11 is so set as to give the necessary pressure upon the piston withinthe cylinder when the swinging frame is raised, and the valve 7 is so set as to regulate the pressure of the fluid passing from the cylinder as the swinging frame is lowered. Suitable steam or air connections are made with the pump Yand with the steam cylinder E, and the pump is set in' operation, the valve 10 in the pipe 3 being open. The cylinder E is drawn back untilit bears against the shoulder q in the frame and i must be steady. uniform and equal, and while the upward movement can be regulated for this purpose, the weight of the frame and the parts carried thereon has a tendency to accelerate the downward rate of travel. It is'also extremely desirable to operate the pump at}! uniform speed or pressure so as to relieve the operator from any care as to the pressure maintained by the pump. It is to accomplish this result that the valve mechanismshown is employed. The regulating valve 11 in the pipe 13 leading from the pipe 12 to the reser voir is set so that itexerts such pressure as to force the oil or other liquid through the pipe or hose 8 and the check valve a into the hydraulic cylinder in such regulated quantity as to move the swinging frame at theproper speed for the upward channeling action, any

surplus liquid from the pump passing through the valve 11 back into the reservoir. This is continued until the swinging frame reaches will fiow past the regulating valve 0. and lift. the check valve and pass freely through the loaf its highest point of movement, when the operator opens the valve 10 in the by-pass pipe 3 and the liquid discharged by the pump then A flows around through such by-pass into the suction pipe 2, the pressure upon the cylinder being thus relieved, and the liquid passing from the cylinder flowing through the by-pass into the suction pipe. swinging frame will, of course, cause the piston within the hydraulic cylinder to descend and the oil flows back through the pipe or hose 8 to the valve 7. Its only escape through such valve is through the opening a controlled by the regulating valve a as the pressure which can be set by the operator, his only duty, so far as the movement of the frame is concerned, is to open and close the valve 10 so as to impart the upward or downward movement to the swinging frame.

duty is the feeding forward of the cylinderE and the clamp and gang of drills connected thereto by turning the feeding screw S. The operation of vertical channeling is continued by the swinging of the frame above and be low its rock shaft or point of pivoting, until.

the cylinder E and the drills are fed out for the full distance of their movement, when it is necessary for the operator to insert a longer set of drills, and the operation may then be repeated. To insert the longer set of drills, the swinging frame is raised to a horizontal position, the clamp H opened and drills Q removed, the rest 14: giving support to the drills and holding them in line both when.

the old set is removed and the new set inserted. In case the gang of drills is of such length as to require a longer rest 14, that is, a rest which would extend farther out from the swinging frame, such rest will be secured inv place before the gang of drills and will act to hold them in line while they are being secured within the clamp. The channeling is then continued as before, the valves 7 and 11 being again set or regulated in case the speed of the swinging frame is to be reduced as the length of the cut is increased. During the entire channeling operation the rest 14 will, if necessary, pass within the channel cut and give support to the drills within such chanme], so relieving the clamp from the heavy strain of supporting the drills against their natural downward movement and providing a guide for the drills within the channel cut and some distance in front of the point of connection thereof to the clamp.

In case it is desired to cut a channel at the corner of the quarry opposite to that part of the machine where the swinging frame is The weight of the This regulating valve a is set to per-' For the opera-. tion of the entire machine the only further mounted, the swinging frame can be loosened from the rock shaft and the swinging frame and hydraulic cylinder moved on the rock shaft, and on thelongitudinal beams V V,

t0 the other end of the main frame, the fiexible or hose connections of the different parts permitting such movement. For. ordinary channeling at difierent points along a breast or wall of considerable length, the swinging frame may be secured about at the center of the main frame so as to distribute the strain evenly throughout the main frame.

I am thus enabled to provide a vertical channeling machine which can cut vertical channels in the walls of the quarry at any point desired; which is simple in construction; and the operation ofwhich can be easily regulated as to the speed of movement of the frame carrrying the cutting mechanism, both in the upward and downward stroke thereof, and which requires only the opening and closing of the valve to reverse the movement of the swingingframe.
